Research areas

Combustion in boilers

Biofuels of different qualities are tested, to find the operating parameters that allow for a complete combustion. Efficiency, emissions and ashes are evaluated according to norm EN 14785.

Pilot scale pellet mill

The pelletization process is optimized for any material varying the compression ratio, moisture and particle size. Pellets are analyzed and tested in the combustion plant.

Fluidized bed and downdraft bed gasification

Research covers different biofuels, gasifying agents and reaction conditions. The heating value and tar content of the gas are obtained.

Physical-chemical properties of biofuels and its effects

The physical-chemical properties of solid biofuels are determined, studying their effect on thermal conversion to energy. Laboratory tests are performed in order to accurately control the different variables of the process. Special attention is paid on properties related to corrosion and ash sinterization, problems that combustion plants have to prevent.

The complete analysis of liquid biofuels can also be performed: cold filter plugging point, acidity and iodine value, oxidation stability test, viscosity and density, water content, fatty acid esters, glycerol (free and total), mono-, di- and triglycerides, PUFAS content, P, Na, K, Ca and Mg, turbidity, lubricity, heating value and distillation.

Biofuels engine tests

These tests are carried out at the facilities of the Fuels and Engines Group in Ciudad Real, both at the School of Mechanical Engineering and at the Research Institute on Combustion and Atmospheric Pollution (ICCA). The biofuel studies are focused on their properties, vehicle performance (fuel consumption, power) and pollutant emissions.
